// Presentation :
//   PclZip is a PHP library that manage ZIP archives.
//   So far tests show that archives generated by PclZip are readable by
//   WinZip application and other tools.
//
// Description :
//   See readme.txt and http://www.phpconcept.net

  // ----- File list separator
  // In version 1.x of PclZip, the separator for file list is a space
  // (which is not a very smart choice, specifically for windows paths !).
  // A better separator should be a comma (,). This constant gives you the
  // abilty to change that.
  // However notice that changing this value, may have impact on existing
  // scripts, using space separated filenames.
  // Recommanded values for compatibility with older versions :
  //define( 'PCLZIP_SEPARATOR', ' ' );
  // Recommanded values for smart separation of filenames.
  define( 'PCLZIP_SEPARATOR', ',' );

  // ----- Error configuration
  // 0 : PclZip Class integrated error handling
  // 1 : PclError external library error handling. By enabling this
  //	 you must ensure that you have included PclError library.
  // [2,...] : reserved for futur use

  //   This method supports two different synopsis. The first one is historical.
  //   This method creates a Zip Archive. The Zip file is created in the
  //   filesystem. The files and directories indicated in $p_filelist
  //   are added in the archive. See the parameters description for the
  //   supported format of $p_filelist.
  //   When a directory is in the list, the directory and its content is added
  //   in the archive.
  //   In this synopsis, the function takes an optional variable list of
  //   options. See bellow the supported options.
  // Parameters :
  //   $p_filelist : An array containing file or directory names, or
  //				 a string containing one filename or one directory name, or
  //				 a string containing a list of filenames and/or directory
  //				 names separated by spaces.
  //   $p_add_dir : A path to add before the real path of the archived file,
  //				in order to have it memorized in the archive.
  //   $p_remove_dir : A path to remove from the real path of the file to archive,
  //				   in order to have a shorter path memorized in the archive.
  //				   When $p_add_dir and $p_remove_dir are set, $p_remove_dir
  //				   is removed first, before $p_add_dir is added.
  // Options :
